Queries the execution results of one or more Cloud Assistant commands on Elastic Compute Service (ECS) instances.

Usage notes

After you run a command, the command may fail to run or may return unexpected results. You can call this operation to query the execution result of a command.
You can query information about command executions within the last four weeks. Up to 100,000 pieces of execution information can be retained.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.
